MARKER. FOR COBN-P LANTERS.

Specification of Letters Patent.

Patented Apr.6,1915.

Application filed September 17, 1913. Serial No. 790,193.

To all whom it may concern Be it known that I, ROLLA E. MUDD, a.

citizen of the United States, and a resident of Stronghurst, in thecounty of Henderson and State of Illinois, have invented a new andImproved Marker for Corn-Planters, of which the following is a full,clear, and exact description.

The objects of the invention are to provide a simple, strong, andinexpenslve marker for corn planters; which can be easily and quicklyattached to any make of corn planter; which is operable from the driversseat; and which will mark on any kind of ground, rough or smooth, hillyor level.

I obtain the above objects by providing a support adapted to be securedto a frame on a corn planter; a marker arm pivotally secured to saidsupport; and means carried by the support and whereby saidarm can bethrown from one side to the other for marking, and, also, can be placedin inoperative position.

The invention consists of the construction and combination of parts tobe more fully described hereinafter and fully set forth in the claims.Reference is to be had to the accompanying drawings forming a part ofthis specification, in which like characters indicate correspondingparts in all the views and in which:

Figure 1 is a rear elevation of a corn planter provided with anembodiment of my invention; Fig. 2 is a plan view of the same; Fig. 3 isan enlarged rear View of the operating lever; Fig. i is a section onl1ne 4.4c of Fig. 1; and Fig. 5 is a line on section 5-5 of Fig. 3.

Referring to the drawings, 6 represents a frame of a corn planter of anyconstruction to the rear portion of which is secured a support 7 formedof two members 8 and 9 connected at the ends and spaced therebetweenfrom each other. The support 7 is secured to the frame 6 in any suitableway, the member 9 being adjacent to the frame and one end of the supportextending to one side of the frame. The secured portion of the support 7is provided with a laterally extending pin 10 lying substantially in thelongitudinal axis of the frame; and mounted thereon by a screw 10 is amember 11 adapted to swing in a substantially vertical plane with thesaid pin 10.

The member 1 11 is. provided with lateral lugs 12 between which ispivotally mounted a marker arm 13. The member ll'is also provided with aspring 14 normally tending to deflect the marker arm from the frame,thereby maintaining taut the flexible element 15 which connects the endof the arm 13 carrying the pointer 16 and the member 17 positioned onthe frontv end of the frame. The overhanging end of the support 7receives a member 18 positioned between the members 8 and 9 and securedthereto. Pivotally secured tothe support, that is, to the members 8 and9, at the overhanging end,

is a lever 19. The pivoted end of this lever is preferably bifurcated;and at'fthe base of the bifurcation it is provided with a centralextension 20 to which is centrally pivoted a link 21. One end of thislink is secured to the member 18 by means of a coil spring 22, while theother end of said link is connected by means of a rodo'r link 23 to thesame member 18. The link 23 has its connection with the member 18 in apoint lying between the pivotal connection of the lever 19 and thespring 22, but closer to the pivoted connection of the lever 19 so thatwhen the lever is in a substantially vertical position the said lever ispast dead center.. The lever 19 is also provided with a pivotallymounted clamping member 2d through which passes a rod 25, one end ofwhich is pivotally connected to the arm 13, the other passing throughthe clamping member. This rod 25 connects the marker arm 13 and theoperating lever 19. By means of the clamping member 24:, the dis tancebetween the arm 13 and the lever19 can be varied. The support 7 is sosecured to the frame 6 that the lever 19 is disposed adjacent the seat26 provided on the frame 6 and from where this leveris operated by.

theldriver. By moving the lever 19 from the position shown in full linein Fig. 1 to the position shown in dot and dash in the same figure, themarker arm 13 is made to swing in a substantially vertical plane aboutthe pin 10 to an upright position shown in dot and dash in Fig. 1. Themarker arm remains in an upright position, as stated, due to the factthat gravity tends to make it fall toward the right and this iscounteracted by the spring 22, which prevents any movement of the lever19 back to the left. To push the mounted arm 13 to the position shown inlower dotted line, Fig. 1, that is,

into the right hand operative position the said arm is slightly forcedby the driver from the seat downward, simultaneously pulling on thelever 19 to bring it to the position shown in full line, thus causingthe arm 13 to take the position shown in lower dotted lines in said Fig.1.

As can be easily seen from the drawings, any unevenness in the groundwith. which the pointer 16 is in contact will cause the arm 13 to moveon its pivot without in any way interfering with the lever 19, which.lever will follow the movement of the arm 13 produced by the unevennessof the ground. If it is desired to increase the ten sion on the pointer16, the rod 25 can be so adjusted by means of the clamp 24 so that thesame will only slightly touch the ground, by being counterbalanced bythe coil spring 2%. The flexible member 15, when the arm 13 is thrownfrom one side to the other, is caused to move on the member 17 from oneend to the other. The spring ii is intended to maintain this flexiblemember 15 in a taut condition.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent:

1. In a marker for corn planters, a sup-- port; a marker arm pivotallymounted on said support; means for swinging said support from one sideto the other operable from the drivers seat and comprising a. pivotallymounted lever, a pivotally mounted link on said lever, a second linkconnecting one end of said link to the support, a coil spring connectingthe other end of the link to the support, a rod connecting said lever tothe arm, the connection of the lever with the arm being eccentric of thepivot of said arm and adjacent the pivot, whereby to move the marker armfrom one side to the other side of the planter, said lever must be movedfrom and back to its original position.

2. In a marker for corn planters v-a support; a member pivotally mountedin said support adapted to swing in a substantially vertical plane; amarker arm pivotally Copies of this patent may be obtained for 1,13a,se1

mounted. in said member; a spring tending to move said arm on its pivotand thereby separate the arm from the member; a lever pivotally mountedon the support; a centrally pivoted link on said lever; a second linkconnecting one end of the firstmentioned link to the support; a coilspring con necting the other end of the link to the support; aconnecting rod from the arm to the lever; and a clamp on said leverengaging said rod and whereby the distance between the lever and the armcan be varied, substantially as and for the purpose set forth.

3. In a marker for corn planters, a support; a marker arm pivotallymounted on said support; an operating lever connected to said support;an adjustable rod connection from said arm to said lever; the connectionof the arm with the rod being eaten trio to the pivot of the arm; aresilient member tending to move the lever in a predetermined direction,and a link from the support to the lever limiting the movement of thelever in said predetermined direction whereby the marker arm is adaptedto be maintained in inoperative position.

4. In a marker for corn planters,a support; a marker arm pivotallymounted on said support; an operative lever associated with saidsupport; a rod connecting the arm to the lever, the connection of thearm with the rod being eccentric to the pivot of the arm; a linkpivotally mounted on said lever; a second link connecting said link tothe su; port; a resilient member also connecting the link to thesupport, said second link limiting the movement of said lever in apredetermined direction, and said resilient member being adapted tomaintain the marker arm in inoperative position when said lever is movedto its limit position in said predetermined direction.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
